According to the operating rate of the granulator and the actual working conditions, the warranty period of the steel belt is generally one year. If used and maintained properly, the life of the steel belt can be appropriately extended. The maintenance methods usually used are as follows:
4.1 When dismantling the distributor during the maintenance process, a thick wooden board or cotton blanket should be placed on the steel belt to prevent the distributor from pressing on the steel belt, especially at the edge of the steel belt, forming a stress concentration point.
4.2 When the positioning rubber strip of the steel belt is loose or falls off, the operation of the granulator should be stopped, and the loose or detached rubber strip should be re-bonded or cut off to prevent the rubber strip from being drawn into the driving roller or driven roller and extruding the steel. band, forming a stress concentration point.
4.3 It is very important to spray cooling water for the steel strip in normal use. It is necessary to ensure that all the nozzles are unblocked, the water quality is clean, and the spray water can cover the entire steel strip, and the water temperature should be kept below 20C.
4.4 Micro-cracks appear on the edge of the steel strip along the axial direction. In order to prevent the extension of the crack, a small hole of 2mm can be drilled at the top of the crack, or the crack of the steel strip can be cut into an arc shape and polished smoothly.
4.5 The compression degree of the scraper at the end of the granulator should not be too tight, otherwise the steel belt will be scratched or torn. The tightness of the steel belt should not be too tight, otherwise the steel belt will deform plastically under tension, reducing the service life.
4.6 When the steel belt deviates, it is necessary to fine-tune the positioning screw in time, and adjust it while turning, and do not stop to adjust or adjust greatly.
4.7 Before opening the granulator, it is necessary to carefully check whether there is any foreign matter in the steel belt, otherwise it will squeeze the steel belt and cause stress concentration. It is necessary to clean up the dust on the water tank, head, tail, frame and steel belt of the granulator in time to ensure that the working environment of the granulator is hygienic and clean.randompackingfactory.com
